Many people use entrenched processes for database development that have been in place so long that it's hard to imagine doing it any other way. In this episode, I share three things that should NOT be normal for database development-- but which are incredibly common. This episode is inspired by the book, "The Unicorn Project", by Gene Kim.

I'm not an expert on collation in SQL Server, but there are a few important facts which I've had to learn the hard way. In this episode I share the basics, along with helpful resources to learn more.

One small localization correction: the default collation on a SQL Server install will be "the oldest available version that's associated with each specific locale." So if your Windows installation has a different localization than mine (which are generally English USA), then you'll see a different default collation -- but it still won't be the recommended collation for *new* development.

Learning Git can be daunting for DBAs. In this 20 minute episode, I discuss why learning a VCS is necessary for DBAs, then give three tips on scoping your project, choosing the right tools, and making sure the project is successful.

So you've got an employee agreement in front of you: now what? In this 23 minute episode, I talk about practical steps you should take to make sure that you understand the terms of your contract, and how to potentially negotiate the terms.

Aug 11, 2018

When you take a new job in software engineering or in IT, within the paperwork there often lurks an employee agreement: a contract between you and your employer. In this half-hour live episode we'll talk about why these contracts exist, and multiple anti-patterns you should avoid.

This is the first of a two part series. In the next episode, we'll talk best practices for understanding and negotiating the contract.

I've gotten a few questions about whether I recommend learning Service Broker, and recently I was asked if I'm planning to make any courses on Service Broker. In this episode, I talk about why I personally haven't become an expert with Broker, the factors that I believe play into Service Broker adoption, and other resources online for learning Service Broker in SQL Server.

This week I discuss a question that I've gotten in many forms over the years - a lot of the scenarios are so specific that it's hard to keep them anonymous, but they can be generalized as a bigger problem: how do I deal with being responsible for things that I can't fully control?

DBAs have huge responsibilities, so this is a common, frustrating scenario. In this episode, I talk about a few times that I've experienced this in my own life, what techniques didn't work, and what strategies were more effective.

A few folks have asked: will auto-tuning and adaptive query plans mean the end of performance tuning jobs in SQL Server? In this week's episode, I talk about why I'm excited about those features rather than afraid of them. Digging into this problem, I share the #1 mindset problem I had as a DBA, why this mindset is so common among database professionals, and a daily habit that can change your approach to new technology.

People have strong feelings about SQL Server Management Studio: they love it AND they hate it. In this week's episode, I talk about why people have such conflicting feelings about SSMS, and how to work it all out.

A query is slow, and you figure out how to collect the query execution plan. Now what? In this episode I talk "big picture" about what execution plans are, what "cost" is, why to collect "compiled for" values, and the steps I take to analyze execution plans while performance tuning queries.

I'll be attending and presenting at the SQL PASS Summit in Seattle Washington this year from Oct 31-Nov 3. In this week's episode, I share why I'm excited about going, and why I've purchased a seat for a pre-conference session. (Spoiler: pre-cons are awesome!) I also give my tips on how to get the MOST value out of a big conference like the PASS Summit.

This week's question from a reader: how do I deal with interview questions asking about real-world scenarios when I've faked three years of experience on my resume?

Aug 17, 2017

In this episode, I talk about three articles written by members of the SQL Server community on interviewing that I can't stop thinking about:
